WGL's Day of Weatherization Prepares Homes Across Region for Winter Conditions

WASHINGTON--(BUSINESS WIRE)--
WGL Holdings, Inc. (NYSE: WGL) today held its fifth annual "Day of
Weatherization," a community initiative helping hundreds of local
residents in need across the region to stay warm and lower heating bills
when temperatures drop this winter. More than 225 WGL volunteers worked
in neighborhoods in Maryland, Virginia, the District of Columbia and
West Virginia on a range of efforts from weatherizing houses to
installing solar arrays.

When volunteers finished today, more than 150 homes across the region
were ready to enjoy reduced energy expenses and added warmth in advance
of the chilly temperatures and icy conditions expected this winter.
According to industry estimates, the typical low-income home saves an
average of 25% on energy consumption and saves an average of more than
$275 annually in heating and cooling costs after weatherization services.

The annual WGL event is a tradition started in 2005 with the company's
regulated utility, Washington Gas, leading the weatherization of area
homes. Today marks the fifth year that WGL's other entities, including
WGL Energy, Hampshire Gas and WGL Midstream, joined together to provide
energy efficiency support to low-income residents across all of its
service territories.

"WGL is proud of our ongoing commitment to support the communities we
serve, and help people in the national capital region to take proactive
energy saving steps as winter approaches," said Terry D. McCallister,
Chairman and CEO of WGL Holdings, Inc., and Washington Gas. "We
appreciate the dedication of our highly valued employees who continue to
give back to the communities we've been honored to serve for more than
169 years."

Throughout the day, volunteers worked to help lower-income families fend
off the cold and reduce energy costs by implementing low-cost upgrades:

installing plastic film on windows;

replacing or installing caulking on windows and doors;

replacing furnace filters;

providing weather stripping; and

installing faucet aerators that reduce the amount of hot water used.

In addition to these efforts, for the third consecutive year, WGL
partnered with GRID Alternatives Mid-Atlantic, a DC-based non-profit
organization delivering solar power to underserved communities, to
support the installation of a roof top solar system on a home in
Northwest, D.C. This is part of the program's initiative to expand the
use of renewable options to lower energy bills and drive energy
efficiency for those in need.
